I've shot already portraits (not head/shoulder shots) with the Rolleiflex without the Rolleinar. Only some issues with proper focussing...
It would help if you'd further discuss your technique: how are you currently focussing (and on what part of the body), are you hand holding or using tripod, is the subject (in the problematic pictures) standing or seated, what shutter speed are you using? What aperture are you using? What type of portrait are you taking and what is the distance between you and the subject? As mentioned much earlier, an example would really be helpful. Also, have you experienced this focus issue with any other type of photography?
There may or may not be "an easy fix" especially since you've already told us, "I have a Rick Oleson spilt [sic] screen ground glass in my Rolleiflex.".
